You are not putting the question but I can guess that it asking for the CD duration. To answer this question, you need to convert the CD capacity unit(783.216 megabyte) into megabits which were used for the cd read rate (1.4 megabits/s). The calculation would be:
CD duration: CD capacity / rate= 783.216 megabytes *(8 megabits/megabyte) / (1.4 megabits /s)= 4475.52 second or 74.6 minutes
